Question

What is the magnitude and direction of Vector GH if G(2, -2) and H(7, 6)?

Answer 1

I have the multiple choice answers if anyone needs it, I just really want to understand how to solve it.

Answer 2

TO find the magnitude,,, U have to apply the formula..... |GH| = \[\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}\]

Answer 3

Can U solve this ?

Answer 4

Yeah, that's distance formula. square root of 89

Answer 5

so, the direction. How do I find it?

Answer 6

write vector GO= 2i-2j and another vector HO= 7i-6j .....now your final vector would be = GO-HO= (7i-6j)-(2i-2j)....after that find the mod of resultant vector that is = \[\sqrt{(a)^2+(b)^2}\] where a and b is coefficient of i and j..you'll get both direction and magnitude

Answer 7

Wait, what is GO and i, j?
